Forged and sharpened by Nigara, the Yorokobi(よろこび) offers a unique copper damascus cladding with the much loved SLD steel. This combination is specially developed by Hatsukokoro, combining excellent artistic with the great performance.

Compared with its previous iteration, the Yorokobi(joy in Japanese) Kurouchi line doesn't fall short in its artistic appearance, in my opinion, Hatsukokoro's artistic approach on this line is more curated and thoughtful. Instead letting the copper damascus spread across the blade, the pattern is restricted in the area right above the cladding line, moving up along the bevel is another layer of iron cladding, then the bevel finishes off into the Kurouchi surface. The layering of different material and their contrast make creates waves of pattern, emerging from the Kurouchi finish, flow down the bevel into the cutting edge, there is almost a sense of motion in it. This setup is rather complex but doesn't look busy, demonstrate a high level of artistic skill.

Complementing this beautiful finish is the SLD core steel, with similar composition to the SKD steel but less chromium, this tool steel can be heat treated to 63-64HRC and hold a thin edge for a extensive amount of time. Having 13%chromium will make it a really rust resistant semi-stainless steel, but on this line the core steel have been put through a chemical etching, which gives it a dark colour and some resistance to rusting and discolouration.

This is a line made for those who fancy the passionate vibe that a copper damascus blade can give you, but don't want have that beauty shouting out loud. The dense orange pattern still emits a strong presence which is hard to miss, but it is well balanced and kept more subtle by the Kurouchi finish that takes up half of the blade. Remember that the copper and the core steel are both reactive to moisture and fingerprints, but if you keep them well looked after, knives from this Yorokobi like can keep bring you joy will its unique beauty.

Pros Cons
  • Great artistic
  • Highly collectable
  • Excellent fit and finish
  • Need extra care
  • Semi-stainless can rust
Care Instruction
  1. Don't cut hard things! Japanese knives are brittle so bone hacking is a NO NO!
  2. Wash with neutral detergent after use, and wipe dry;
  3. Please don't wash knife with dishwasher, it will damage the wood handle;
  4. Be careful not to leave the knife close to a heat source for a long time;
  5. It is a lot more dangerous to cut with a blunt knife than a sharp knife!
  6. It is best to sharpen a Japanese knife regularly on a waterstone.
  7. Semi-stainless steel won't rust easily but may still patina

Hatsukokoro

Hatsukokoro, a knife brand from Amagasaki

Hatsukokoro (初心) is a knife brand from Amagasaki, Hyogo, launched in 2019. It is a brand rather than a forge: it works with knife makers instead of forging itself.

The name comes from the proverb 初心忘るべからず, roughly never forget your beginner's mind. For the same characters the brand chose the gentler reading hatsukokoro over shoshin.

The brand's own catalogue names the place behind some of its lines, and the maker behind a few: Shinkiro comes from Fukushima, and Hayabusa HAP40, Saihyo and Sunaarashi from Seki City, while for others the maker or the place stays private. Some of our listing titles also carry the maker alongside the brand, such as Hatsukokoro x Yoshikane and the Hatsukokoro x Yoshihiro Yauji collaboration.

The Hatsukokoro lines we list include both carbon and stainless steels. Our listings include Hayabusa in SG2 and Aogami Super, Saihyo in SG2 and Ginrei in Ginsan. Carbon steel kurouchi lines include Aosagi, Aokitae, Kurokaze and Kurogane.

“A knife brand from Amagasaki that works with knife makers rather than forging.”

Frequently asked questions

Is a K-tip Gyuto the same as a traditional Kiritsuke?

Not quite - and it is the single most common point of confusion when people shop for a kiritsuke. The two knives share the same striking angled, reverse-tanto tip, but underneath that tip they are very different tools.

A K-tip gyuto is normally a double-bevel knife: it is ground on both sides like any Western-style chef's knife, so it is forgiving to use, and sharpened exactly the way you would sharpen a normal gyuto. You get the dramatic kiritsuke look with the everyday usability of an all-purpose chef's knife.

A traditional kiritsuke, including the kiritsuke-yanagiba (slicer), is a single-bevel knife, ground on one side only. It is historically a master chef's knife: it takes real practice to use well, is set up for right-handed users by default, and needs single-bevel sharpening technique to maintain.

So if you want the kiritsuke silhouette with no learning curve, choose a K-tip gyuto. If you specifically want the traditional single-bevel discipline - and the precision it allows on fish and vegetables - choose a true kiritsuke. At Knives and Stones we stock both, and each product page tells you which construction you are looking at.

Is SLD the same steel as SKD11 and D2?

Close. Proterial, which makes SLD, lists AISI D2, DIN X153CrMoV12 and JIS SKD11 as its equivalent standards, while its own typical figures include 12% chromium and 1.5% carbon.

Proterial makes SLD as a cold work die steel with high abrasion resistance, for uses such as cold press dies, shear blades and gauges.

Is Hatsukokoro a maker or a brand, and who makes the knives?

Hatsukokoro (初心) is a brand, not a forge. H&K, a company founded in 2013 and based in Amagasaki, Hyogo, created it in 2019.

H&K names the producer for some lines, for example Shinkiro by Takahiro Nihei in Fukushima, Ginyou by Yoshihiro Yauji in Echizen and Kurosagi by Motokyuichi Hamono in Nagasaki, and keeps others confidential. Some knives we stock carry the maker in the title, such as Hatsukokoro x Yoshikane SKD Nashiji.

What does the name Hatsukokoro mean?

The name comes from the Japanese proverb 初心忘るべからず, which means don't forget your original intention. The company read it gently as hatsukokoro rather than shoshin.

H&K created the brand in 2019, six years after the company was founded, and chose the name for its knife line.

Which Hatsukokoro line should I pick, carbon or stainless?

Pick by how much care you want to give. The carbon lines, Blue 1, Blue 2 and AS kurouchi, need drying and a little oil after use. The SG2, HAP40, Ginsan and VG10 lines are low maintenance, so they suit a busy kitchen or someone who just wants to cook.

Neither is better; it depends on your routine. If you will dry and oil the blade after each use, a carbon line can suit you, and if you want the least fuss, a stainless line is the easier choice.
